A parent should have a say in what their kid reads and sees, but A) using this as an excuse to get rid of books that don't fit a particular world view is horrible, and B) by the time a kid is in school, they should be exposed to things that make people uncomfortable (age appropriate of course). Its how people learn and grow, and something that people, adults and children, should be encouraged to do.
But it's not just the books under fire now that worry me. It is the books that will never be written. The books that will never be read. And all due to the fear of censorship. As always, young readers will be the real losers.
